Gilead reports study of E/C/F/TAF met primary endpointGilead Sciences announced detailed 48-week data from an open-label Phase 3 study evaluating its investigational once-daily single tablet regimen of elvitegravir 150 mg, cobicistat 150 mg, emtricitabine 200 mg and tenofovir alafenamide 10 mg, or E/C/F/TAF, among 1,436 virologically suppressed adult patients switching from tenofovir disoproxil fumarate-containing regimens. The study met its primary endpoint by demonstrating non-inferiority of E/C/F/TAF to the TDF-based regimens at Week 48. The study also demonstrated statistical superiority among patients with HIV-1 RNA levels less than 50 copies/mL at Week 48 and statistically significant improvements in bone and renal laboratory parameters. These data were presented in an oral session at the 8th IAS Conference on HIV Pathogenesis, Treatment & Prevention in Vancouver, Canada. Among the 1,436 patients who were randomized in the study, virologic success rates at Week 48 were higher in patients taking E/C/F/TAF, 97% versus 93% for all TDF-based regimens; difference in percentages: 4.1%, 95% CI: 1.6% to 6.7%. The rates of virologic failure were similar between the two arms, with E/C/F/TAF, 1.0% and TDF-based regimen, 1.3%. General safety was similar between the two arms through 48 weeks of treatment, with similar percentages of patients in each group having any adverse events. Adverse events leading to treatment discontinuation were more common among patients treated with a TDF-based regimen.
